Abstract

PURPOSE:To make efficient use of a thermally sensitive transfer paper by attaching each thermally sensitive monocolor recording paper to a single thermally sensitive recording paper unit, then transporting a thermally sensitive transfer unit to a thermally sensitive head unit consisting of a single thermally sensitive head for recording. CONSTITUTION:When paper 1 transported by a transport roller 2 reaches a thermally sensitive head 3, the resistor of the thermally sensitive head 3 is selectively heated, then a thermally sensitive transfer paper 4 becomes molten and the ink is transferred to the paper 1. Thus data is recorded and the thermally sensitive transfer paper 4 is taken up by a thermally sensitive transfer paper winding motor 9. When data is recorded in other colors, a thermally sensitive transfer paper change-over motor 10 rotates to permit a thermally sensitive transfer paper unit 8 connected to a belt 11 to slide. Subsequently, a roller 12 on an arm 6 moves along the recessed part 13 of the unit 8. Then the thermally sensitive head 3 rides over the winding part of the thermally sensitive transfer paper 4, 5 and becomes positioned at a printing location for the thermally sensitive transfer paper 5. Thus the thermally sensitive paper can be used effectively.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the structure and mechanism of a recording section (printing section) in a multicolor thermal recording device using a thermal head and thermal transfer paper.

[Conventional technology]

Conventional equipment applies multiple colors (usually three colors) to a fixed length of thermal transfer paper, and then repeatedly coats the paper to form the thermal transfer paper, and the recording section sequentially selects the transfer colors. As is well known, there are some. However, in this case,
There was wasteful empty feeding of the thermal transfer paper, and there was a drawback that the thermal transfer paper was not used effectively. Also, JP-A-57-129
As described in No. 762, a pair of thermal heads and thermal transfer paper are used to perform single-color recording, and multiple pairs are arranged to perform multicolor recording, making effective use of thermal transfer paper. .

[Problem to be solved by the invention]

However, as mentioned above, in the above-mentioned conventional technology, thermal transfer paper cannot be used effectively, or it is composed of multiple thermal heads and thermal transfer paper, and there is no radial retraction mechanism when the thermal transfer paper is attached, Separate paper winding mechanisms are required, making the mechanism complicated.

The object of the present invention is to enable thermal transfer paper to be used effectively and to
The purpose is to simplify the recording mechanism by using a single thermal head for multicolor binding.

[Means to solve the problem]

In order to achieve the above object, each monochrome thermal recording paper is attached to one thermal recording paper unit, and the thermal transfer unit is successively conveyed to the thermal head unit consisting of one thermal head for recording.

In addition, a convex part is provided on the thermal transfer unit, and when the thermal transfer paper unit is conveyed and the thermal transfer paper is switched, the thermal head unit is lifted up by the convex part of the thermal transfer unit and retracted from the thermal transfer paper. In this way, the mechanism is simplified.

[Effect]

During recording, the thermal transfer paper in the thermal head unit is wound up by the thermal transfer paper winding mechanism installed near the thermal head unit, and other thermal transfer paper is not wound up, making it possible to use the thermal paper effectively. can.

In addition, each thermal head unit is composed of a thermal transfer paper winding mechanism, and when switching between thermal transfer papers, the thermal head unit is retracted by the convex portion of the thermal transfer paper unit! This eliminates the need for a separate retraction mechanism, making it possible to simplify the mechanism.

〔Example〕

One implementation of the present invention will be described below.

As shown in Figure 1, paper 1 is set in the paper insertion slot.
is transported by a transport roller 2, the thermal head 3 welds the thermal transfer paper 4 to the paper 1, and the thermal transfer paper 4 is attached as necessary.
. Further, as shown in FIG. 3, thermal transfer paper 4.5 is attached to each thermal transfer paper unit 8.

Here, when the paper 1 conveyed by the conveyance roller 2 reaches the thermal head 3, the thermal head 3 is rotated.

The antibody is selectively heated, the thermal transfer paper 4 is melted, and the antibody is transferred and recorded onto the paper 1. Further, the thermal transfer paper 4 is wound up by a thermal transfer paper winding motor 9. When recording in other colors, when the thermal transfer paper switching motor 10 rotates and the thermal transfer paper unit 8 connected by the belt 11 slides, the roller 12 of the arm 6 moves along the convex portion 13 of the thermal transfer paper unit 8. As a result, the thermal head 3 passes over the winding portion of the thermal transfer papers 4 and 5 and is set at the printing position on the thermal transfer paper 5. FIG. 2 shows a state in which the thermal head unit crosses over the convex portion of the thermal transfer paper unit.

Although this embodiment describes two types of thermal transfer paper, it goes without saying that three types of thermal transfer paper can also be used by similarly mounting three types of thermal transfer paper in a thermal transfer paper unit.

Further, as shown in FIG. 4, when the thermal transfer paper unit 14 is fixed and the thermal head 15 is connected to the link 16, and the thermal head switching motor 17 rotates, the link connected to the belt 18 rotates around the fulcrum 19. , a mechanism in which the thermal head 15 is switched is also possible.

4. However, this mechanism for switching the thermal head 15 requires a platen 20 and a thermal transfer paper winder, making the mechanism somewhat complicated. .

The thermal transfer paper mounting portion of the thermal transfer paper unit is provided with a means for identifying the spool shape corresponding to each transfer color, such as providing a concave and convex portion that individually corresponds to and fits with each spool of thermal transfer paper. This makes it possible to prevent erroneous operations such as inserting thermal transfer paper of a different color.

□As mentioned above, according to this embodiment, each of the monochromatic,
Since n types of thermal transfer paper are each mounted on nine thermal transfer paper units, and the thermal transfer paper units are successively conveyed onto the thermal head and wound up, the thermal transfer paper can be used effectively. In addition, by switching the thermal transfer paper unit to a thermal transfer paper, multicolor recording can be performed with a single thermal head, and since the thermal head retracts when the thermal transfer unit is conveyed, the mechanism can be simplified. .

Note that this method is particularly suitable for devices such as bank terminals that require red and black printing and that mostly have black printing.

〔Effect of the invention〕

According to the present invention, n types of thermal transfer paper, each of a single color, are mounted on one thermal unit, and the thermal transfer paper units are successively conveyed onto the thermal head, so that only the thermal transfer paper on the thermal head is Since it is rolled up, thermal transfer paper can be used effectively.

Furthermore, by switching the thermal transfer paper in the thermal transfer paper unit, multicolor recording can be performed with one thermal head, which simplifies the mechanism and reduces costs.
